Herbert Lawrence Anderson (born May 24, 1914 in New York City , † July 16, 1988 in Los Alamos ) was an American nuclear physicist.

Anderson studied at Columbia University (bachelor's degree in 1931, in electrical engineering in 1935), where he received his doctorate in 1940 with John Ray Dunning (1907-1975). During this time he was instrumental in building a cyclotron under the direction of Dunnington. He also built other laboratory equipment such as ionization chambers and amplifiers. In January 1939 he was a member of the first team in the USA that repeated at Columbia University the experiments of Otto Hahn and Fritz Straßmann on nuclear fission, which had recently become known through lectures by Niels Bohr at Princeton . Under Fermi he experimented further to study nuclear fission and was also one of its most important assistants (with Walter Henry Zinn ) in the construction of the first nuclear reactor in Chicago in 1942. Anderson then directed the construction of the CP-2 reactor at the Argonne National Laboratory and was a consultant for DuPont building the breeder reactors in Hanford .

After the war he went with Fermi to the University of Chicago , where he was Assistant Professor from 1946, Associate Professor from 1947 and Professor from 1950 (Distinguished Service Professor from 1977). 1958 to 1962 he was director of the Enrico Fermi Institute there. After working repeatedly at the Los Alamos National Laboratory , he joined the laboratory in 1978 and stayed there until his death, most recently as a Senior Fellow.

He died from the effects of beryllium -Verseuchung of the lungs ( beryllium disease ), which he drew upon forty years previously in experiments in Fermi's laboratory.

In 1932 he became a Fellow of the American Physical Society . From 1955 to 1957 he was a Guggenheim Fellow and 1956/57 as a Fulbright Lecturer in Italy. In 1982 he received the Enrico Fermi Prize . He was a member of the National Academy of Sciences (1960) and the American Academy of Arts and Sciences (1978).
